Cohen, D., and R. G. Wanner (Division of Safety, NIH, Bethesda, MD 20205). The case of the intoxicated cells—an epldemlologic note. Am J Epidemiol 1981;113:250-3. An episode is described In which tissue culture In a laboratory could have become Intoxicated due to the reclrculation of toxic exhaust fumes extruded from the roof of a research Institution. A route of entry was found whereby a porti...

The paper introduces a genetic algorithms based elevator group control system utilising new approaches to multiobjective optimisation in a dynamically changing process control environment. The problem of controlling a group of elevators as well as the basic principles of the existing single-objective genetic elevator group control method are described. The foundations of the developed multi-obj...

In this research paper an attempt has been made to integrate the programmable logic controller (PLC) with elevator for developing its control system. Thus, this paper describes the application of programmable logic controller for elevator control system. The PLC used for this project is GE FANUC with six inputs and four outputs. The programming language used is ladder diagram.

purpose: to evaluate the clinical manifestations and surgical results in patients with double elevator palsy operated at labbafinejad eye center from 1993 to 2004. methods: the study was conduct on hospital records of 20 patients with double elevator palsy. patients were classified in three groups including primary elevator muscle palsy (9 subjects), primary supranuclear palsy with secondary in...

An account is given of a theoretical flutter investigation in connection with an accident to a Sea Venom aircraft. The investigation covers both symmetric and antisymmetric flutter of the tailplane-elevator-tab system. The main (symmetric) calculations include six degrees of freedom, comprising three structural modes and movements of elevator, spring-tab and trim-tab respectively. The parameter...

Development of space proven technologies, fundamental research in microgravity and preparation future missions all benefit from next generation drop tower facilities like the Einstein-Elevator. The facility is being made available within a DFG core center Hannover.

The safety climate of an agricultural workplace may be affected by several things, including the level of trust that workers have in their work group supervisor and organizational management. Safety climate has been used by previous safety researchers as a measure of worker perceptions of the relative importance of safety as compared with other operational goals. Trust has been linked to severa...

In this paper we introduce a fuzzy elevator group controller using a linear context adaptation technique. We first describe the elevator group control problem and the schemes usually employed to solve it. We detail the fuzzy controller used in our development and an example system used in simulation experiments. The focus is on the comparison between the standard fuzzy controller and the fuzzy ...
